ennAsn-nxsrnnsme DEVICE.

A pplieation filed February 1926, Serial;'No.-89,740. Renewed October le -1927i Thisv invention relates ":to improvements in devices formetering liquids or semi-liquids,

' andfparticularlydealswith a device espe- Y ciallyintended for use by garage and" service station rnento dispense grease and the like.

" Such stations are frequently called uponto. feed grease to" different housings of an automobile from abulk supply, and it is of course to the advantage of bothythe' ser- Theprincipalfobject of my invention there fore is to provide a device' for this purpose by ineansof which an'accurateand controlled amount of grease will-be dispensed with each movementof a control handle; For

instance supposing a device is'made'tohold a" pint of theliquid; six movementsor' the control handle will indicate that sin pints' no more and no lesshave been jdispensed.

"The parts of thedevice are constructed in such a *waythatthere-is 'very'little likelihood of any leakage taking place, such as wou1drenderthe amount dispensed to be inaccurate.

A further object of the; invention is "to i provide means for enabling grease to bedis- ;pensed ffromf'the device without sueh grease passing through the metering structure if. desired,

i'While the "device is especially intended for the above purpose", it is also suitable for the dispensing of gasoline and other liquids;

lAYfurltherfobject of the invention is to produce a: simple and inexpensive device and ;,yet; one which 'will'be' exceedingly effective (for the purpose for which it is designed.

"These objects ITaocom'plishhby means of such structure and relative arrangement of parts asuwilli fully ,-appear by ap'ersual of thei'following specification and claims; I

ingturned after openingsvon the under side of said plate. Another-passage 11 *extendsfr'om the bot hole19therethrough and a 'curvedgroove 20 19 and groove 20 are concentrievvith' the orifice 1st and the other passage openings, and having the same arcuate spacing as said various openings, it will be seen that the hole 19 may register with the passage 9, while the groove 20 registers simultaneously with the orifice 1st and passage 11; or the hole 19 may register with the orifice 14 while the groove 20 registers simultaneously with the passages 10 and 11.

The valve has a. downwardly projecting and substantially rectangular stem 21 which has aslidable and non-turnable fit in a spindle 22. This spindle is turnably mountedin a cap 23 secured to the plate 3 and cylinder 1 in spaced relation to the valve. This spindle is provided with a tapered flange 2st which has a seat in a similarly shaped recess inside the cap. A compression spring 25 about the-spindle presses the valveconstantly against the plate andthe flange 24 into its seat. In this manner leakage past the spindle and between thevalve and plate 3 is prevented at all. times, since the spring takes up wear as it occurs. A turning handle 26 isapplied to the outer end of the spindle.

The cap 23 has. an intake opening 27 in its bottom to one side of the spindle, for connection to a supply pipe or to a tank in which grease or other material being dispensed is maintained under a suitable pressure. The cap also has a tapped side outlet 28 below the valve, for connection to a hose or toreceive a plug.

In operation it will therefore be seen that if the valve is turned to place the opening 19 into alineinent with the passage 9, and the groove 20 into alinement with the opening 14 and passage 11 grease will be fed through the passage 7 to the corresponding end of the cylinder and will bear against the plunger at that end. The grease being under pressure said plunger will be forced toward the opposite end of the. cylinder and with this movement a previous charge of grease in the cylinder below the plunger will be forced by the movement oi? the latter through the opening 1 1, along the groove 20 into the passage 11 andthence to the outlet 13.

hen the plunger has reached the opposite end of the cylinder the valve reversed in position so that the coenings 19 and ii register and the groove 20 registers with the passagesll and 10. Grease will then enter the body through the opening let, the plunger will move in the opposite direction and the grease already fed into the body from the opposite end will now be forced out through thepassages 8 and 10 to the groove 20 and thence to the outlet. These movements are of course carried out as many times as may be necessary to dispense the required amount of grease. y

It will be noted that before any grease can pass through the outlet 13, it must first raise the plunger l i. This of course causes the stem 15 to raise also, and the stem thus provides visible indication to the operator as to whether any grease is passing through the outlet or not. Assoon as the body is emptied of grease the plunger is returns to its outlet closing position by reason of the spring 17.

It will be seen that with movement of the plunger in either direction the same amount of grease will be dispensed in both 1 cases. The set screw 5 is rovided for :the purpose of enabling the istance through which the plunger 4:.11'13) travel to be accurately set so that the amount dispensed will be an exact unit of measurement such use pint or a quart, or whatever size' capacity the device may be made to have.

If it is not desiredto measure to be dispensed, the valve is moved tea neutral position, so that it does not re 'ster with any of the plate o enings .an the grcaseis allowed to pass directly out of the out-let 28. This enables small amounts of it irom such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
